The new patchset is prepared, but a bit stucked at internal review.

In short, changes in it are the following:
- USE_CCACHE="1" in `local.conf` is used in to enable the feature in general.
- USE_CCACHE="0" can be set in the recipe to avoid caching even if it's 
enabled in general
- ccache.bbclass was removed the main ccache-related variables were placed to 
bitbake.conf.
